WEATHER-STRIP.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed May 20, 1918. Serial No. 235,592.

To all lwhom it may concern:

Be it known that I, HECTOR MCKINNON, a citizen of the United States, residing at Eureka, in the county of Humboldt and State of California,.have invented a new and useful Weather-Strip, of which the following isa specification. Y

The device forming the subjectmatter of this application is a weather strip adapted to be mounted on a Ydoor or other swinging closure and the invention aims to provide novel means for mounting the weather strip and for controlling the movements thereof, so that the weather strip will be swung away from the threshold when the door is opened, and be swung downwardly upon the threshold when the door is closed.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and'other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is an elevation showing a door to which the device forming the subject matter of this application has been applied;

Fig. 2 is a vertical section showing the actuating means at one end of the strip;

Fig. 3 is a vertical section showing the actuating means at the other end of the strip;

Fig. 4 is a perspective view showing the tiltable member whereon the weather strip is mounted;

Fig. 5 is a composite elevation showing parts of the bearing wherein the tiltable member is journaled; and

Fig. 6 is a fragmental sectional detail showing in elevation, a slight modicationV in the invention.

Numerals 1 and 2 denote door ambs, the oor being shown at 3, and the numeral 4 designating the threshold. The numeral 5 marks a horizontally swinging door or other closure.

In carrying out the present invention there is provided a casing 6 which may be variously constructed without jeopardizing the utility of the structure hereinafter described. If desired, the casing 6 may be madeof metal and may include-a back 7, bent at its upper end as shown at 8, to form an outwardly extended brace strip 9, bent at its lower end as shown at 10, to ferm a curved top 11 disposed in the arc of a circle, the lower edge of the top 11 and the lower edge of the back 7 being united as shown at 12. Securing elements 14 pass through the brace strip 9 and the back 7, near to their upper edges, and connect the casing 6 with the door 5. The casing 6 includes end walls 15 secured to the back 7, the brace strip .9 and the curved top 11, the end walls f.

having vertically elongated slots 16..

The invention comprises a tiltable member, denoted generally by the numeral 17 and located within the casing 6. The tiltable member includes a body or plate 18,

which may be made ofmetal, the body 18 having shafts 19 at its ends, the shafts being received for rotating movement in the verti-l cally elongated slots 16 of the end walls 15 of the casing 6. One shaft 19 has an arm 20 which extends downwardly with respect to the body 18, the other shaft 19 having an arm 21 which is disposed approximately parallel to the'body 18.1 U-shaped kbearings 22 are secured as shown at 23 to the end walls 15 and receive the shafts 19 for rocking movement. Retainers 24 are received between the arms of the U-shaped bearings 22 and are notched at their ends as shown weather strip preferably being made of rubber or some other resilient material. The body 18 of the tiltable member 17 is supplied with holes 29, adapted to receivey any suitable means for securing the strip 27 to the body 18.

A track 30, which may be a thin strip of metal, is counter-sunk in the. threshold 4 and is adapted to coperate with the arm 20. An actuating member 31, inclined with respect to the vertical, is secured to the j amb 2, and is pivoted at 32 to the jamb 2, the track 30 being located adjacent to the Jamb 1. Adjacent its lower end, the actuating member 31 is provided with a transverse slot 83 through which extends a securing device 34, such as a screw, the securing de# vice entering the janib 2. The arm 21 on the tiltable member' 17 is adapted to coact with the actuating member 31.

In practical operation, when the door 5 is swung to an open position, the arm 2O cooperates with the track 30 on the threshold 4, and therefore with the threshold, to swing the tiltable member 1T and to elevate the forward edge of the weather strip 27 from the threshold. When the door 5 is swung to a closed position, the arm 21 coacts with the actuating member 31 and swings the tiltable'member 17 so that the weather strip 27 bears on the threshold 4, as shown in F 2.

lt is to be observed that the upper edge of the weather strip 27 slides in contact with the curved top 11 of the casing 6. Consequently, air cannot blow through above the upper edge of the weather strip. Since the end walls 15 Of the casing 6 are provided with the elongated slots 16, it is possible to adjust the tiltable member 17 vertically,the U-shaped bearings 22 and the retainers 24 being adjusted also in a vertical direction.

AOwing to this adjustment, the weather strip 27 may be made to cooperate with the threshold et and with the curved top 11 of the casing 6. The actuating member 31 may be swung vertically on its pivotal mounting 32 and may be held in adjusted positions by tightening up the securing device 34; which engages the jamb 2. The actuating member 31, therefore, may be so positioned that it will cooperate properly with the arm 21 and secure a tilting on the member 17, when the door 5 is swung to a closed position.

In Fig. 6, a slight modication of the invention is shown. In this figure, parts hereinbefore described are designated by numerals previously used, with the suffix a ln this form of the invention, the arm 2Oa is provided at its lower end with a roller 35 adapted to Vcooperate with the threshold 4C. V7hen the forms shown in Fig. 6 is resorted to, the track 30 may be used or not, but or dinarily, the track is omitted when the roller 35 is supplied.

Having thus described the invention, what is claimed is V In a device of the class described, a doorcarried casing including a curved top and ends; a tiltable member bearing continuously at its upper edge against the top and provided at its ends with shafts having` arms, the lower edge of the tiltable member being adapted to cooperate with a threshold, and one arm being threshold-operated to raise the lower edge of the tiltable member when the door which carries the casing is opened; bearings receiving the shafts; ineansfor securing the bearings adjustably to the ends of the casing thereby to take up wear on the upper edge of the tiltable member and to permit said edge to cooperate with the top-of the casing; a jamb-carried actuating member cooperating with the other arm to press the lower edge of the tiltable member against the threshold when the door is closed; and means for securing the actuating member to a jamb in adjusted positions, whereby the actuating member. will cooperate with the last-specified arm when the bearings are adjusted.

ln testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

HECTOR MCKINNON.
